retrieve the path of a saved image causes crash

Question

is it there a standard way to retrieve the path of an saves image taken by the camera, because i found different ways to display the path but they cause the App to crash. and since i'm new to android programming i just need some guidance. Please check the code:

Java Code:

@Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            Intent imageIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            File imagesFolder = new File(Environment.getExternalStorageDirectory(), "My Images");
            imagesFolder.mkdirs();
            File image = new File(imagesFolder, "img01");
            uriSavedImage = Uri.fromFile(image);
            File f = new File (uriSavedImage.getPath());// <---------
            //imageIntent.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage);
            imageIntent.putExtra(MediaStore.EXTRA_OUTPUT, f.getPath()); // <---------
            startActivityForResult(imageIntent,CAMERA_REQUEST_CODE);
        }
    });
}

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if ((requestCode == CAMERA_REQUEST_CODE) && (resultCode == RESULT_OK)) {

            Toast.makeText(getApplicationContext(),// <---------
                    " "+data.getData(), 
                    Toast.LENGTH_SHORT).show();

can you paste the stack trace here ? – Triode Mar 21 '12 at 15:46 — Triode, Mar 21 '12 at 15:46

It crashes because you pass getParent() to convertImageUriToFile method (you can see NullPointerException in the stacktrace). According to android docs getParent() returns null if activity is not an embedded one. Yours most probably isn't.

Use File f = convertImageUriToFile(uriSavedImage, this); instead.

For another error, imageUri being null, see this aswer for very possible explanation and solution.

Morover, your imageUri is a "file://" type uri, not "content://" type.To get path from it, use

new File(uri.getPath());

instead of your convertImageUriToFIle() method. I think that method will work only for "content://" type uris.

Actually, you do not need to get the file path from uri you made yourself, you have that path in the line:

File image = new File(imagesFolder, "img01");

`Toast.makeText(getApplicationContext(), " "+convertImageUriToFile(uriSavedImage, this).getAbsolutePath(), Toast.LENGTH_SHORT).show(); ` I tried to display the path as mentioned, but still the app crashs – Androelpha Mar 22 '12 at 08:46
Provide a stacktrace if you want help. – Tomasz Niedabylski Mar 22 '12 at 11:31
Isn't your imageUri null? There is nullPointerException during query execution. Check if you imageUri is not null and is in proper format (starts with content://) – Tomasz Niedabylski Mar 22 '12 at 16:06
i assign value to imageuri, but it's null – Androelpha Mar 22 '12 at 16:24
please check the code again i modified onActivityResult() method – Androelpha Mar 22 '12 at 16:26
i modified the code, please find it posted. But now the app doesnt crash and it displays null. Note that, i'm using the emulator not a real device – Androelpha Mar 23 '12 at 09:10
